I can't find "tools" on the firefox desktop so I can subsequently clear privacy data

In error, I asked firefox to remember my AOL password on a friends computer... which I am now using. Each time I sign on, my mail opens up automatically. I was told to go to TOOLS in the Firefox desktop and click on CLEAR PRIVACY DATE and then select EVERYTHING. The problem is I can't find the word TOOLS in the Firefox main page

*Press F10 or tap the Alt key to bring up the "Menu Bar" temporarily if the Menu Bar is hidden.
*Use "Firefox > Options" instead of "Tools > Options" to access Options if the menu bar is hidden.
